Marinette Dupain-Chang woke up on a dreary day in Paris. For a moment, she forgot that she had responsibilities as Ladybug, and rolled over and prepared to go back to sleep. She was interrupted by her Kwami, Tikki, who was jumping on her chest. "Come on, Marinette, wake up! It's Valentine's Day and you never mailed your letter to Adrien." She squealed. Marinette shot out of bed, accidentally knocking Tikki across the room. "Oh no!" she moaned, slumping to the ground. "And it's a weekend, so there is no school, and since it's a Sunday, there isn't any mail service, and the only way I would be able to deliver it is by going to his house. I'm DOOMED." At that moment, Tikki happened to glance out the window, and she squeaked in terror. "Looks like you might have to worry about that later. Someone has been Akumatized!"

Hawk Moth paced back and forth within his lair, scheming, plotting, planning. Then, just as he was about to change back and hang up his Miraculous for the day, he detected a huge surge in negative energy. "Finally. Another wayward soul, struck down by the intricate hell that is Valentine's Day." He snatched a butterfly out of the air, and clasped it between his hands, motes of blackness consuming it. He released it toward the open window, and growled "Fly, my terrible Akuma and show that child the true power of love." The butterfly flew off, toward a very lonely teenager.
